HEEL-'NAILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 358,298, dated February 22, 1887.

Application filed November 26, 1886. Serial No. 219,900. (No model.)

To all whom. it may concern:

Be it known that I, Fnnnnonn F. RAYMOND, 2d, of Newton, in the county of Middlesex and f State of Massachusetts, a citizen yof the United States, have invented a new and useful Tmprovement in Heel-Nailin g Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

The invention comprises a heel-attaching machine having a nail feeding and distributing` device of peculiar construction.

It relates also to devices for arranging nails for delivery to a distributer, and to the combination of said devices vwi th the nail-driving devices.

It further relates to various details of construction and organization.

In the drawings, Figurel is a'plan view of the parts of the machine to which the invention especially relates. Fig. 2 is a vertical section taken upon the line m x of Fig. l, and' also showing parts of the heel-attaching devices.` Fig. 3 is a vertical section upon the line y y of Fig. 1. Fig. 4 is a vertical section upon the dotted line z a of Fig. l.

Ais thelast-Or work-support. It is mounted upon the spindle a, which is supported by the 3o jack-post a. Bis the templet. Itis supported by the vertically-movable table b.

Gis the crosshead. It carries the revolv ing head c, which is adapted to be automatically revolved, and which has an arm supporting a block carrying a gang or group of awls, c', an arm supporting ablock carryinga gang or groupv of drivers, (not shown,) and a spanker-arm, which may or may not have toplift-holding devices.

Dis the nail-carrier. I-t is movable from the distributer E to the templet B, and is adapted to carry cr transfer nails from thelistributer to the templet. The distri buter` comprises the block e, having the holes e', of the arrange ment of the holes in the nail-carrier and templet, the block e, which has a straight line of holes, e", preferably at uniform distances apart, and the tubes e", which connect the block e3 with the block e2, and form the passages efrom the holes e3 to the holes c'. These tubes are bent or curved forward so as to permit the block e to be placed as near the templet as possible to shorten the throw or extent of movement of the nail carrier or transferrer D. This distributer is made removable from the machine.

Above the distributer is a plate7 F. This has also a line of holes, f, which corresponds in location with the line of holes in the bloeie, and this plate supports a block, G, which is adapted to be rotated upon the pin or cen ter g, and which has formed therein the radial lines of holes g. These holes are placed quite closely together, so as to provide the block with as large a number of lines of holes as possible. The block is so pivoted or arranged in relation to the block e2 ofthe distributer that the .various lines, g', of holes are adapted upon the turning of the block to be brought in line with the holes f and holes e3 of the block e2, and so as to discharge nails therefrom directly intrJ the distributor, and the block being mounted upon an imperforate iiat plate, F, the nails cannot escape from the lines of holes g until they are brought in register with the line of holes j. Y

The block G may be revolved by hand; but I prefer to rotate it automatically with an intermittent movement, and for this purpose I have provided mechanism for moving it upon this center g intermittingly, so that the various lines, g', of holes are brought in successive order in register with'the holes f.

The mechanism which I have shown coniprises a pawl-arm, H, pivoted upon the stud h, which attaches the block G to the bed or plate F, and below the said bed, so that the l arm shall be underneath the block, instead of over it, and thereby leave the entire upper surface of the block G unobstructed. This arm carries near its outerend the spring-pawl h', which is adapted to engage the rat-chetteeth h2 upon the outer edge of the block G, and upon the movement of the arm H to rotate the block aportion of a revolution or the length of one tooth. This arm H is provided with a swinging or oscillating movement at given intervals upon its center It, by means of the cylinder-cam H upon the cam-shaft h", (see Fig. 3,) the rock-shaft 71.* having the campn r", which enters the groove of the cylindercam, and the arm or lever h, at the upper end of the rock-shaft, which has a slot, h?, which receives the pin 71,8, extending upward from the arm H.

In order that the lines, g, of holes may register with the holcs f, it is necessary to automatically lock the block G when the line of holes has been brought into registering position; and this is obtained by means of the latch or locking bar M. (See Figs. 1, 3, and 4.) This block M is pivoted to a bracket, in, m', so that its end mi shall have a vertical movement in relation to the surface of the block G, and there is formed upon the surface of the block G about i ts edge the ratchet-teeth or projections in, which are parallel with the ratchet-tceth h, but are opposed thereto. The latch or locking bar M also has the end m", (See Figs. l and 4,) which projects over the movable curved arm or lifting device mi', and attached by the lever It and arm m to the rockshaft h4. This lifting-arm m5 has the lower flat surface, m7, (see Fig. 4.,) the inclined surface ma, and the upper iiat surface, m, and the end m4 of the latch-bar M is maintained in contact therewith by the spring ml". (See Figs. I, 3, and 4.) Upon the movement of the lever it to move the feed-pawl h and the block G, the arm 'n is moved under or beneath the end m of the latch-bar, and the latching end of the bar remains lifted or elevated, so that the tooth m3, which it was last in contact with, may pass under it, and until the arm mi has been moved sufficiently to bring the incline mB beneath the end mt, when'the latch end M is moved downward into a position to act as an abutment or stop for the projections or teeth m, and after being moved into this position it is held in such position by the flat surface in? of the said arm, and the movement of the lever 71," and feed-pawl h continues until the stop or tooth a comes in contact with the side of the locking-bar M, when it ceases, and the block G is held rigidly between the lockingbar M and the end of the feed-paw] 71,', and when the block is in. this position one of the lines, g', ol' holes is in register with the holes f, and the cam is timed to deliver nails to the distributer, preferably once in every three reciprocations of the cross-head, or one gang for everyheel attached. The time for this delivery may vary; but preferably it is immediately after the carrier has taken from the distributer a previously-fed gang or group of nails.

To hold the block G during the reverse movement of the feed-pawl to engage the next tooth in order, I use a detent-pawl, N, which prevents the block G from being moved backward bythe drag of the feed-pawl upon its rc` verse movement. The latch-bleek M remains in operative position `until the feedpawl has very nearly reached the end of its backward movement, when the removal of the raised part of the arm mi from beneath its end m4 allows the spring to operate to raise the end on, so that the block G cannot be moved backespecially adapted for the latter use; and while y it may be rotated by hand to deliver nails to the distributer, I prefer that it be rotated automatically, as that relieves the boy or attendant froin so much work, and gives him more time to supply the holes g with nails. By this device it will be seen that the boy or attendant can work in advance of the operation of the machine to an extent sutlicient to enable one boy to attend to two machines.

I would say that I do not confine myself to the especial movements herein described for providing the block G with the automatic movements specified, but may use in lieu any mechanical equivalents for the devices mentioned.

In use the holes g are supplied with nails, and upon the Starting of the machine the block G- is rotated sufficiently to advance one line, g', of holes to the distributer. This, however,takes but an instant, and during the remainder of the movement, and at all other times, the plate G is stationary, so that the feed of the nails to other lines of holes can proceed as rapidly as desired. The nails are delivered from the block G 1 trough Lne soles of the distributer to the carrier D, and by it they are advanced to the nail-driving devices, preferably automatically.

While I have represented this device as applied to a heel-nailing machine, I would say that it can be used with any nailing-machine adapted to drive nails in a gang or group.

I would further say that while I have shown the invention as applied to or embracing a plate having a series oflines of nail receiving and holding holes, which lines of holes are adapted to be brought in consecutive order in line with the holes ofthe distributer, yet I do not wish to be 'understood as limiting the invention to the use of a rotary plate, as a slideplate having parallel lines of holes, and having an intermittent feeding movement, so that its lines of holes are brought consecutively in line with the lines of holes of the distributer, would be the same thing.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the Ur ted {states-- 1. The combination, in a heel-nailing machine, of heelnailing devices, the nail-distributer E, the block G, having the lines, g', of holes, and the ratchet-teeth h2, with the arm H, pivoted to the stud 7i, and the spring feedpawl 71,', carried thereby, substantially as described.
